Q. How does gastric bypass surgery work to help with weight loss?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Gastric bypass surgery helps with weight loss through a combination of restrictive and malabsorptive mechanisms. Here's how it works:
1. Restriction of Food Intake: The surgery creates a small upper stomach pouch by dividing the stomach into two parts. This small pouch can hold only a fraction of the food you could consume before the surgery, typically about an ounce or so. As a result, you feel full after eating a small amount of food, which naturally limits your calorie intake.
2. Early Satiety: Because of the small pouch, you experience early satiety, meaning you feel full much quicker during meals. This helps reduce the quantity of food you consume in one sitting and decreases your overall calorie intake.
3. Malabsorption of Calories and Nutrients: Gastric bypass surgery reroutes a portion of the small intestine, bypassing the lower stomach and the initial segment of the small intestine (duodenum). This bypassed section of the digestive tract is responsible for absorbing a significant portion of the calories and nutrients from the food you eat. By redirecting food past this section, the surgery reduces the absorption of calories and nutrients, leading to additional weight loss.
4. Changes in Hormones: Gastric bypass surgery can also result in changes in the production of certain hormones, such as ghrelin (the hunger hormone) and incretin hormones. These hormonal changes can help reduce appetite and improve blood sugar control, contributing to weight loss and improved metabolic health.
Overall, gastric bypass surgery is effective in promoting weight loss by both restricting the amount of food that can be eaten and altering the way the body absorbs calories and nutrients. However, it's important to note that the degree of weight loss varies from person to person, and the long-term success of the procedure depends on adherence to a post-surgery diet and lifestyle changes. Additionally, individuals may experience different rates of weight loss and improvements in obesity-related health conditions following the surgery.
Q. Hello Doctor, from past 3 weeks I have too much dandruff problem and it cause hair loss will you suggest any best solution for this?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
